Study On Liquid Fertilization On Rubber Tree

For a long time,solid-state fertilize was mainly used in crops. However, with the application of solid-state fertilizer in the soil for a long time, it brought a lot of problems as well. In order to meet the need for continued development of modern agriculture, there is an urgent need for us to continue to seek new fertilizer. Recently, liquid fertilizer was applied to the crops as a new type of fertilizer, and it obtained a significant effect. Studies have shown that liquid fertilizer can supplement plant nutrient quickly and efficiently, and it can increase crop yields and improve crop quality. But the research of liquid fertilizer on rubber trees was few. This experiment studied the effect of liquid fertilize on rubber seedlings and cut open trees in order to provide the basis for application of liquid fertilizer on rubber trees.This paper studied the effect of rubber seedlings and rubber trees after sprayed by liquid fertilizer. The research of organic liquid fertilizer was studied by mixed different organic nutrients at3levels which were sprayed on rubber seedlings of Reyan7-33-97having two Punta leaves. And the physiological parameters of rubber seedlings leaves and latex were studied. All the physiological parameters of rubber seedlings and latex were studied by foliar application of trace fertilizer at3levels. The results are as follows:1Study of organic nutrients liquid fertilizer1.1Effects of organic nutrients liquid fertilizer on rubber trees Good effects of organic nutrients liquid fertilizer on rubber trees. The contents of N, P, Mg in rubber seedlings leaves significantly increased at60mg/kg(Gly+Lys+Leu+Cys+Orn)+300mg/kg humic acid. Latex yield and dry rubber contents were significantly higher than other treatments at40mg/kg(Gly+Lys+Leu+Cys+Orn)+200mg/kg humic acid.1.2Effects of organic nutrients liquid fertilizer on rubber treesGood effects of organic nutrients liquid fertilizer on rubber trees. The nutrient contents of N,P,K and Mg in latex were significantly higher than other treatments at600mg/kg(Gly+Lys+Leu+Cys+Orn)+3g/kg humic acid. Latex yield and dry rubber contents were significantly higher than other treatments at600mg/kg(Gly+Lys+Leu+Cys+Orn)+3g/kg humic acid.2Study of trace elements water-soluble fertilizer2.1Effects of trace element fertilizer on rubber treesGood effects of trace element fertilizer on rubber trees. The nutrient contents in rubber trees leaves were significantly improved, and the contents of chlorophyll were significantly improved. and the growth of rubber seedlings were significantly promoted on foliar spraying trace element fertilizer at2.5mg/kg. The petiole plastic value of rubber seedlings were significantly improved on foliar spraying trace element fertilizer at3.5mg/kg.2.2Effects of trace element fertilizer on rubber·treesGood effects of trace element fertilizer on rubber trees. The nutrient contents of P, K, Mg and dry rubber contents in latex were significantly higher than other treatments on spraying trace element fertilizer at lOmg/kg.In summary, the nutrient contents in rubber trees leaves were significantly improved, and the contents of chlorophyll were significantly improved, and the growth of rubber seedlings were significantly promoted by foliar spraying liquid fertilizer on rubber seedlings. The nutrient contents, latex yield and dry rubber contents in latex were significantly higher than other treatments by spraying liquid fertilizer on rubber trees.
